Answer:

y = -4x - 1

Step-by-step explanation:

Parallel lines have same slope

y = -4x + 1 {Compare y = mx + b; m ->slope; b - y-intercept}

m = -4 ; (-2 ,7)

y - y1 = m(x - x1)

y - 7 = -4(x - [-2])

y -7 = -4(x + 2)

y -7 =x *(-4) + 2*(-4)

y -7 = -4x - 8

y = -4x - 8 + 7

y = -4x - 1

The correct answer is the first option, which is:

A=G^2/H; H=G^2/A

The explanation is shown below:

1. To solve the exercise shown in the figure attached, you must apply the proccedure shown below:

2. You have the following equation to calculate G:

G=√AH

3. Now, to find the formula to calculate A, you must clear the A, as below:

G^2=(√AH)^2
G^2=AH
A=G^2/H

4. Then, you must apply the same proccedure to find the formula for calculate H, as following:

G^2=(√AH)^2
G^2=AH
H=G^2/A
